OIL-BURNER.

Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed May 5, 1913. Serial No. 765,609.

To all whom it may concern Be it known that we, RALPH B. WARNER and MELVILLE L. SHROAT, citizens of the United States, residing at Marion, in the county of Grant, State of Indiana, have invented a new and useful Oil-Burner, of which the following is a specification.

This invention relates to improvements in oil burners.

An object of the present invention is to provide an oil burner which may be readily positioned within a stove and will effectually heat the same.

A further object is to provide improved means whereby the air will be heated prior to its mixing with the gaseous fuel to thereby increase the efliciency of the burner.

A further object is to provide improved means whereby the liquid fuel will be effectually vaporized prior to its issuing from the delivery nozzle.

l Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction herelnafter described and claimed, 1t belng understood that changes in the precise embodiment of lar reference numerals designate corresponding parts throughout the several views, 1 is a base with a cover or lid 2 fitting thereover, the said base and lid forming an air chamber 3 through, which the air passes prior to its mixing with the fuel'to form a combustible mixture. The base 1 and cover 2 are provided with the outstanding lugst through which extend the bolts 5 to thereby provide means whereby the cover may be rigidly and at the same time detachably secured to the base. The rear end wall 6 of the air chamber extends a slight distance above the side walls and rigidly secured thereto is the outstanding plate 7 upon which rests the U-shaped box member 8, the same comprising a top and two side walls which taken in conjunction with the upstanding portion 9 of the cover 2 forms a continuation of the air chamber or passage 3 and is offset a distance thereabove.

The cover or lid 2 is provided with two complete inclosing upstanding flanges 10 which thereby define two open pans or receptacles l1 and 12. The pans in question are used during the initial starting of the burner and serve as means for containing a limited burned to thereby generate sufficient heat to vaporize the liquid fuel which after having been once lighted, generates-suificient heat to maintain the fuel in a vaporized condition. The upstanding plate 9 disposed at and defining the rear end-of the cover or lid 2 is spaced adistance away from the end wall 6 of the base 1 so as to allow suiiicient space for the passing of the air through the boxlike member 8 down into the air chamber 8.

Arranged approximately longitudinally central of the pans 11 and 12 and adjacent the front ends thereof are the upstanding mixer tubes 1313, the same being formed integral with the cover-2 or may be rigidly secured thereto and the central opening 14:

which extends therethrough communicating. with the air chamber 3 as more clearly illustrated in Fig. 2 of the drawings.

From the foregoing it will beapparent that the air after it enters through the open end of the box-like structure 8 which is adapted to extend through the outer wall.

of the stove to which our improved burner is to be attached, passes downward through the opening between the lid 2 and end wall 6 of the base 1 and into the air chamber 3 and becomes heated during the said. passage and passes upward through the mixer tubes 13. in a highly heated condition, it being noted that the entire burner is formed of smet-al and therefore readily conducts the ;heat from points throughout the entire structure.

adjacent the flame,

A liquid fuel supply pipe 15 is provided .Wlt-ll the coupling 16 from which the two fuel supply pipes 17 lead, the samecommunicating with the control valves 18 which are preferably of the needle type. Leading from the two valves 18-18 are what are termed the feed pipes 19-19, the same extending through the open end of the boxlike structure 8, extending downward into which the fuel, which at V to deflect the flames the air chamber or passage 8, and extending along the under surface of the cover thereof. The pipes l9-19 pass upward through the cover 2 at points adjacent the rear ends of the pans 11 and 12 communicating with the upstanding pipes 20-20 to a height above the top of the mixer tubes 13 across which the pipes 20-20 then pass as at 2l21. The feed pipes then dip downward as at 2222 and communicate with what are termed the fuel delivery nozzles 23-23, the same extending horizontal and passing through suitable apertures in the side walls of the mixer tubes 13-18 as illustrated. he delivery nozzles 23 are provided with the upwardly directed openings 2a through this point will be in a gaseous state, issues. In order to provide means whereby the delivery nozzles 23 may be cleaned at various times, the plugs 25 are threadedly secured to the ends thereof. The liquid fuel entering through the fuel supply pipes 17 passes through the regulating valves 18 and down through the air chamber 3 along the under surface of the cover, whereby the fuel will be heated. The fuel then passes upward through what are termed the fuel feed pipes which lead directly above and across the mixer tubes 13. A suitable deflector is mounted upon the said feed pipes 21 and comprises a broad flat plate adapted in the usual manner and also to absorb a certain quantity of the heat therefrom and conduct the same to the feed pipes 21 to thereby successfully vaporize the fuel prior to its emission or exit from the supply nozzles 23. By providing the metallic base and cover which defines a suit-able air chamber therein, the air will be heated prior to its mixture with the gaseous fuel, with the result that a high degree of efficiency will be obtained and that a highly combustible mixture of air and gaseous fuel will be obtained. Packed joints such as unions, etc., are disposed out of and at considerable distance from the burner with the result that little or no trouble will be experienced by a burning outof the packing disposed within the same. The pans 11 and 12 provide means for the burning of an initial charge of liquid fuel to thereby heat up the various parts of the burner for the vaporization of the liquid fuel which may be any suitable liquid such as gasolene, kerosene, or other suitable hydro-carbon.

Having thus fully described the invention, what we claim to be new and original with us is 1. An oil burner including a trough-like base, a cover therefor, mixer tubes extending through said cover and communicating with the air chamber defined by said base and cover, said cover stopping short of one end of said base allowing the ingression of air, delivery nozzles extending through the side walls of said mixer tubes and adapted to deliver gaseous fuel therein, and fuel feed pipes extending above said mixer tubes communicating with said delivery nozzles and extending through said trough-like base.
